How to Select the Right Continuous Gas Analyzer?


How to Select the Right Continuous Gas Analyzer?


✔  Deciphering Your Needs

The first step is to decipher your needs. If you’re dealing with a process involving 30% CO2, for example, an analyzer capable of handling a greater range than a process with just 5% CO2 is necessary.

Customizing the analyzer to your unique specifications enhances productivity, sidesteps undue costs, and mitigates the danger of inaccurate data. Clarity on which gases are to be detected, anticipated concentration spans, the nature of the sample gas (moist or dry), and the environment of application is critical.

Keep in mind the desired data outputs, interfaces, and foreseeable future demands. Forward-thinking ensures the analyzer’s adaptability, averting premature obsolescence.

✔  Evaluating Gas Composition and Concentration Range

The composition of the gas and its concentration range are key to choosing an analyzer. A multi-gas analyzer is required for intricate gas streams containing several elements, such as a flue gas comprising SO2, NOx, CO, CO2, and O2.

For detecting trace levels, an analyzer with high sensitivity is necessary, capable of detecting gases at parts per billion (ppb) levels.

A comprehension of the gas stream’s concentration range is vital. An analyzer capable of measuring 0-500 ppm wouldn’t be sufficient for a process involving 1000 ppm of a specific gas.

✔  Considering Measurement Precision and Sensitivity

Precision in measurements and sensitivity are critical. An analyzer with a margin of error of +/-1% outperforms one with +/-5%. Sensitivity – the capacity to detect alterations in gas concentration – also merits attention.

In scenarios where minor variations are significant, such as environmental monitoring, heightened sensitivity is key. Analyzers with a lower detection limit (LDL) under 1 ppm are typically employed in these cases.

✔  Accounting for Environmental Conditions at the Application Site

Environmental conditions at the application site can impact the performance of the analyzer. A factory situated in a region with an average temperature of 35°C, for instance, necessitates an analyzer resilient to high temperatures.

Similarly, a corrosive environment calls for an analyzer constructed with materials resistant to corrosion. The existence of dust or moisture might call for supplementary sample conditioning systems to safeguard the analyzer.

✔  Gauging the Analyzer’s Durability and Reliability

The durability and reliability of an analyzer ensure seamless, prolonged operation.

An analyzer engineered for a lifespan of a decade is more beneficial than one designed for half that time, factoring in the cost of replacement and potential operational downtime.

A reliable analyzer also lessens the frequency of maintenance, conserving resources.

✔  Cost Evaluation

The cost isn’t limited to the initial purchase. The overall cost of ownership also includes installation expenses, upkeep costs, and operating expenditures. While energy-efficient analyzers may come with a higher initial price tag, they can lead to long-term savings.

✔  Adherence to Regulatory Standards and Certifications

Compliance with regulatory standards and certifications is a testament to the analyzer’s performance and safety.

Adherence to standards like ISO 9001 and ISO 17025 signals quality and dependability. In the same vein, certifications like ATEX or UL guarantee safe operation in hazardous environments.

It’s important to ascertain that the chosen analyzer complies with all relevant standards and certifications pertinent to your geographical region and sector.
